Would it be wise to use a Heloc for a down payment on my first investment property?

I was originally considering house hacking with a multiplex (and I have over six figures I could put for a down payment) in Philadelphia but it seems that the only places where I could cash flow right now would be in far west philly or in neighborhoods that are boring or not so safe, would be a longer commute to work areas, etc. 

Unfortunately, this means that I have to let this deal go, but it made me come up with a couple of questions about this situation:Does anyone have experience in partnerships where one partner's only real requirement is to sit on the loan and potentially provide interest payments when needed during the duration of the construction? 

@Brian Howse hey @Ather Taqui, if you do a umbrella policy it will cover liability and medical payments on all of your investment properties.

We often end up finding out their credit score or income doesn't cut it only after we've shown them around, which honestly feels like a bit of a time sink.So, I was thinking, whenever someone hits us up on Zillow wanting to check out the place, maybe I could just ask upfront if their credit score is over 600 and if they're pulling in more than $6,000 a month.

In some situations, a lender will allow for someone who didn't originate the loan to continue making payments, until the lender changes their mind.

@Samson Oni I accept Check, certified payments, Venmo, CashApp, Zelle, Facebook Pay.

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

As of now, I have saved up enough money for a down payment on a fha loan, and my income is expected to meet the loan qualification criteria soon (with my parent co-signing due to my limited income history).

Financial aide payments are not always the most consistent.
